Please note: This adapter is NOT intended for standard 1kg spools (due to the dimensions of the original holder, the spool would no longer fit). It is specifically designed for smaller, typically 250g spools.

Stop the spool wobble! This simple, functional upgrade is designed specifically for the external spool holders of the Bambu Lab A1 and A1 Mini.

Standard holders often have a significant gap between the shaft and the spool bore, leading to uneven rotation, "jumping" of the spool, and inconsistent filament tension. This centering adapter ensures your spool rotates perfectly smoothly, leading to better print consistency and reduced mechanical noise.

Key Features:

• Universal Fit: Designed for spools with a hole diameter from 45mm to 58mm.
• Improved Rotation: Eliminates wobble and reduces friction for a consistent filament feed.
• Simple Design: Easy to print and install in seconds.
• Compatibility: Works perfectly with the stock external spool holder on Bambu Lab A1 series.

Technical Specifications:

• Min. Spool Bore: 45 mm
• Max. Spool Bore: 58 mm
• Material Recommendation: PLA, PETG, or even TPU for extra grip (though PLA works perfectly).
